Introduction to PHP 6/13
Strings
A string is a word or phrase between quotes, like so:
"Hello, world!"
You can type a string all at once, like this:
<?php
echo "Hello, world!";
?>
Or use the concatenation operator, which glues several strings together:
<?php
echo "Hello," . " " . "world" . "!";
?>
The concatenation operator is just a dot (
.). (If you're coming to PHP from JavaScript, the dot does the same thing for strings that +does in JavaScript.)
